Package texlive-patgen

http://tug.org/texlive/

Patgen takes a list of hyphenated words and generates a set of
patterns that can be used by the TeX 82 hyphenation algorithm.
Patgen was originally written by Frank M. Liang as part of his
Stanford Ph.D. work, and has always been distributed alongside
the other programs coming from the Stanford TeX project. It was
updated in 1991 by Peter Breitenlohner for the new 8-bit
features of TeX version 3. (These updates related to
input/output and programming overhead; the actual pattern
generation algorithms were not changed.) Patgen is currently
maintained as part of TeX Live.
